Description

The USA Standard Gear ZMNIS-5C is a replacement 5th gear set specifically engineered for manual transmissions in compatible Nissan vehicles. This "regular" grade component features a 21/39 tooth count, designed to fit 1993 and newer Nissan 4-cylinder models. It is intended as a direct replacement for the original 5th gear, aiming to restore or enhance transmission performance. This gear set is compatible with several Nissan models, including the 1987-1994 Nissan D21 (4WD), 1995-1997 Nissan Pickup (4WD), and the 1998-2004 Nissan Frontier (RWD and 4WD). All listed applications utilize the FS5W manual transmission and are specified with a 2.4L L4 engine. As a drivetrain component, it is crucial to ensure correct fitment before purchase. This part is sometimes subject to special order status, which may include cancellation or return restrictions.
